PRINTING MECHANISM.

Specmoation of Letters Patent.

To all whom 'it may concern:

Be it known that I, HARRY C. GAMMETER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga. and State of Ohio,have invented a certain new and useful Im rovement in Printin Mechanism,of whic the following is a fu l, clear, and exact description, referencebeing had to the accompanying drawings.

'This invention relates to rinting maf chines of the type commercie lyknown as the multiv aph, wherein there is a rotary printing typ and asuitable platen coperating therew1 The features comprised in the resentinvention are the means for pro r locating the type on the drum andlildling them against endwise displacement; the mechamsm for guiding thesheet as it asses`between the drum and platen, and t e mechanism forfinally ejecting the paper so arranged that it and the means for holdingthe type are ad'ustable lengthwise of the drum, so as to allow theassemblage of matr ter of different widths and the e]ection of papercorresponding thereto.

The object of the invention is to present these features in simple andeiicient mechanism. Such mechanism is hereinafter more fully describedin connection with the drawings.

a portion of the drum together with the fasl tening devices of the typehold' band; Fig. 13 is a perspective view of t e t ho din band, the samebein broken out 1ntermediately, and Fi let 1s a perspective of the edgeguide for e paper.

In the embodiment shown4 in the drawings, there is a suitable base Afrom which rises a pair of vertical parallel standards 0r end plates Aand A. Journaled in these lates is a main driving shaft B 'on which 1smountfxl the printing drum B. The surface of this drum as shown in Fig.12 is provided with undercut ooves b for the reception of type C whichhave laterally extending feet, whereby they may slide lengthwise of theooves but are held therein against latera and outward movement.

An suitable means is provided for allowing t e type to be assembled onthe drum.

Fig. 1 shows at a a suitably formed guiding channel across the framemember A by which the type may be slid to and from the printing drum.Beneath the printing drum is a. rotar impression platen D connected withthe rum by gears b and dillo vthe drum and laten respectively; `The rilmhas a considerable opening in its periphery, adjacent to which itcarries a air of spools E. lA suitable inking ribbon 1s adapted to becarried by these spools passing around the drum. A crank B2 is-shown asproviding means for rotating the drum. When the drum, having typeassembled on it and a ribbon passed around the type, is rotated, papermay be drawn between the drum and platen and thereby be printed. l

As the type are freely slidable along the drum, it is necessary to havesome means to prevent their displacement, and this means should besodevised that it ma be adjustablv positioned on the drum to low matter ofdierent widths to be assembled thereon. This type holdingV meansl mustalso be of such character that it does not project farther than thetype, so that it mayl pass rbetween the drum and platen withoutimpressin or marring the aper. I have found t at the desired resu ts maybe very etliciently accomplished by one or more steel .bands F each ofwhich is roviaed at its end vwith hooks These terva1s,say at distancesequal to y ands are passed around the m adjacent to the ends of thelines of 'ty thereon and the hooks are hooked over t eed of the drum atthe oplening therein, as own in Figs. 1 and 12. T e hooks .f may be veconveniently made o f wirefbent into a. U ape intermediately and havingthe ends crossing each other and4 `preferably on the bases of the typegrooves,

as indicated by the dotted lines in Fig. 1. By means of the bands thematter on the 'drum' may not ,only be very conveniently locked to thedrum, but the bands being accurately positioned by the guiding marks,the pro er and` uniform margin 1s maintained or all the lines. Shortlines, as at the ends of paragraphs, may be held at one end bysuitablerubber plugs Vset into the grooves, as 1s well understood.

The mechanism which grips the paper and feedsit, includin the feedrollers and stop fingers herein s own, is the subject late throughopenings in Va,`

'of my Patent No. 846,992 granted March 1'2,

1907.- The mechanism for controlling such feed rollers and timingthereof shown herein is covered in my divisional application No.396,571, filed Oct. 9, 1907. For completeness, both .mechanisms will Ybe'described herein. l

As shown in Figs. 2, 3, 4, and 7, g represents a shaft on Vwhich aremounted sleeves G forming an interrupted roller projecting orlzontalrame plate As constituting a table. This roller has a gear g meshingwith an idler g2 which meshes with the gear d on the platen. Above therollers G is a roller H mounted at its ends in pivoted arms, of whichthe right hand one is shown at H. This arm H is extended inwardlyandcarries a roller zl which is adapted to be engaged and depressed by acam K carried by l the printing drum. Such depression maini as tains theroller H out of engagement with the rollers G, as shown in Fig.v 3.

J represents lingers adapted, to project through. openings in the' tableA, these lingers being rlgidly mounted on a rock shaft y'. A spring jsurrounding this rock shaft tends to keep the fingers with their uturned ends projecting above the plane ci) the table and into engagementwith the miler H 0n the forward end of the arm H is an extension Itwhich has a downwardly extending `lug adapted to bear on Va rook arm i2on the shaft j. When the parts are in the position shown in Fior. 3 (thecam engagm the roller h) the s eet of paper isshoe by hand across thefront portion of the table A3 until its rear edge is. stopped by fingersJ.

When the cam clears the roller a spring h2 swings the cam roller upward,bringing the forward end of the arm H' downward.

This movement vthrough the extension h swings the rock shaft j and drawsthe lingers .J downwardlyout of the way of the paper.

At the same time the roller H descendlng, comes on` the paper and movesit between itself andthe rollers G, t-hese latter rollers beingconstantly revolving to feed the paper so that it passes between thedrum and the f impression platen. The forward ,end of the spring h2 enages in a series of notches in a stationaryV ar h3, whereby the force ofthe spring-may be adjusted. The paper feed mechanism is partly hiddenfrom view by the shield and paper guide a2 carried at the vfront of themachine.

When the sheet of paper is placed in position against the ngers J, oneedge of the paper at least lies beneath the metal strip N. This stripextends from beneath the roller H rearwardly across the barrel d of theimpression platen and adjacentto the softsurface l2 thereof. Beneath thestrip N is a strip N' the forward portion of which curves downwardlyaround the upper part of the platen barrel, the two str1ps extendingrearwardly in arallelism from a point adjacent to the hlghest line ofthe platen. The parallel portions of the two strips are brought togetherat their outer edges and are carried by'a sheet lmetal bracket N2 whichis secured to the tableplate A3. In the preferred form, the two stri s NN and the bracket are a single integra piece of sheet metal bent onltself as shown in Fig. 14. This luiding structure is supplied at eachend of the raised surface to the impression platen. If the paper is of afull width each edge is guided by these strips. If the paper is narrowerthan the full width, one edge is guided, which has been foundsuilicient.

It is desirable to maintain the feed rolls out of coperation during aconsiderable portion of the rotation of the drumso as to allow ampletime for placing the sheet against the stop fingers; and it is also de-Vspondiii to the length of the cam. The 'roll' h, owever, is broad enoughto eiitend across both cams,-wherefore should one cani 4be shiftedbeyond the other, the eii'ective is; .ength ofthe cam is increased up toa maxiiiiutn of-'twice the length of either cam member. By this meansthe paper feed may -befheldoutlof act-ion for as great or short periodas desired.' One of the cams is lstationary and is of a'lengthcorresponding 2519-, and 11. In the end member o the drum, adjacent tothe surface` b on which the cams seat, is a recess adapted to beoccupied b i blocky L. This block has a shoulder or ri l along its upperedge which isadapted to occupy a 'correspondin notch in thecam rin K,thereby securely ocking this -rin to t e d rui'n. The block extendso'iitwar y beneatlithe cam ring K. In the block is a threaded hole whichis occu ied b n,-"-"cap screw l. This screw passes t roug an Lsha ed clil, which bears on the outer side of t e bloc and against the cam ring Kand projects into the recess beneath the block, thereby holding the ribl inthe notch in the cam ring K. The cagi vrings are held by the gear band the okl of the drum against movement longituia ly ofthe The blockholds t e ring'K against rotative movement, and the cam ring K holds theblock against displacement by .rea-son of the shoulder Z. Whe n the capscrew Zfis loosened, the 'cam rin K is therebyl unlocked and may beshifte circumferentially to shorten or lengthen the effective 48 cam, asdesired. A recess k is made in the `inner face of this cam to allow the'insertion Y oiga-screw driver or other tool for convenz iently shiftingthe cam.

'B reason-.of` lthe 'L -shaped clip I, the- I locking block L ma beeasily putin place. The height of the s oulder l is slighy less than thethickness ofthe piece l. herefore when this piece is removed, the blockmay be slid into the recess beneath the cam rin K, the block then beingmoved outward ra ially, the rib l passes into lplace behind the' ring'K. The ieee Z* is t en put' into "lace as a filler to old the block inthis position. 1

i60 When-the movable cam K has been adroperlytime the paperjusted andlocked to feed according 'to t e letter head on the paper, a rotation ofthe drum causes the apex' to be 'fed rearwardl rum and platen, one orbotl edges of the 'a belt pulley. `A belt gi t.

between the,

paper passin between the strips ofthe edge guide or gui es. In suchoperation, it sometimes happens that the friction of the sheet of paperdevelops suilicent frictional electricity to give it a tendenc to clingto the plrinting drum, so that as t e paper emerges om the guiding stiis, it is carried around toward t e front o the machine by the printingdrum,V and iin-less removed, will a ain pass through the printingmechanism.

is diiilculty does not ordinarily occur, but

in cold dryweather it sometimes happens,

especially if the pa er be light and iiexible.

To overcome the di culty mentioned I provide an ejeeting mechanismadapte to receive the paper as it is emerging from the 'printing couple,and prevent its wra ping around the drum. This mechanism is s own inFigs. 2,' 5, 6, and 7. Mounted on the end frame member Ais a4 pinion pwhich carries connects this with a pulley p2 on the sha p which iscarried between tlieframe members, extendin parallel Awith the platen,as shown in ig. 6. This shaft is carried at one 'end by a removable studp, extending into an opening in the shaft and at the/other end by 'ascrew p, which projects, ito an opening in that end of the shaft. Thisshaft p carries rollers Pwhich pro'ect upwardly througlh open- 96 insin* the tab e A". Extending orizonta y across the machine near its rearedge is a rod .Q on which are slidabl mounted ariiis R in the form ofcages w ich carry freely 'ournaled rollers S adapted to bear upon t erollers P. `The pa er being fed rearwardly in a substantie horizontalplane along the top ofthe table, runs between the rollers S and P, whichcontinue to guide it so that when the paper is freed 105 rom the guidingstrips, it is not able to come up onto the drum and cling thereto.

As heretofore stated, the bands F` which I have provided allow matter ofvarious size to be locked on the drum. For example, it may be desired toprint postal 'cai-ds. -In this case,lone of the bands ma be near the.end of the drum and the-ot er near the middle. Where the type page is ofthis short width, the paper is of correspondingly narrow width, andhence isided by only one of the guiding clips at t e ends of the platen.When the paper ejector is used, onl one of the end rolls P would comeinto action with such narrow paper. I. accord-'120 i'ngl provide one ormore intermediate rolls. In t e embodiment shown, there is oneintermediate roll -1: which is ordinarily suf,-v

eient, as it is seldom desirable to print on 1 paper materially less"than half Ithe width ,ofA the drum. But two rolls S need be pro-1vided,l 'because their car ing members-R I are slidable upon the roda,So that the two rolls 'S may be made to copera-te withany twoof therolls P, according to the position 1430 tion of a printing memberhavinglon tudi nal type holding channels, type in sai chan of the bands F onthe printin drum. To

furnish convenient means for s lifting these` rolls S, I form tails orextensions ron the members R by which they may be easily taken hold ofby the fin ers. etween the two ears of the cage, whic surround the rodQ, I place a split. sleeve r which engages this rod with sutiicientfriction to prevent accidental dis laceinent of the cage 1, whileallowing it tolbe shiftedv when desired.

The arts constituting the paper ejector are ma e so that they may beconveniently removedwhen it is not desired to use them. When they are inplace, it is simply necesto thirr rol sin accordance with the osition ofthe bands F and theej-ector is ready for use.

The ejectingmechanism per se is covered in `my divisional applicationNo. 459,343, filed Oct. 24, 1908; it is claimed herein only incombination with the printing couple and th nlutually adjustablemarginal band.
